WebNov 7, 2013 · As the motor temperature increases and the curve becomes steeper, shaft speed will drop more for the same increase in load. Equation 4a – Theoretical Motor … WebMar 29, 2024 · For example, the temperature rise of the 50 hp (37.5 kW) motor in Table 1 is 75°C (135°F) at full load; if the load increases to the SF of 1.15 (57.5 hp/43 kW), it goes to 102°C (184°F)-an increase of 27°C (49°F). In that case, the motor may last only 15% as long as originally expected: Life 1.15 = Life 1.0 X 0.5 (ΔT/10) = 1 X 0.5 27/10 = 0.154 chris hindle cheshire east council
